Here is the code I have right now. It’s purpose is to place an event listener on every button with the same class using querySelectorAll and some loop (currently using forEach), and make it a togglable "fav", toggling which will add or subtract 1 from the text in the span inside the button: const likeButtonArray… Read More Why do I get the "can't read properties of null" error, when using "querySelectorAll.forEach"?
there is a need to check the data entered by the user and display a notification on the screen in case of incorrect input. I used the following method, but it seems to me that it don’t quite fit into the principle of "don’t repeat yourself". Does anyone have any ideas for simplification? int productid… Read More A "dry" principle case
Say I have a Filter interface public interface Filter { public boolean satisfies(Earthquake earthquake) } Which can have different implementations (one such below) public final class MagnitudeFilter implements Filter { private final double minimumMagnitude; private final double maximumMagnitude; private final ComparisonStrategy strategy; public MagnitudeFilter(double minimumMagnitude, double maximumMagnitude, ComparisonStrategy strategy) { this.minimumMagnitude = minimumMagnitude; this.maximumMagnitude =… Read More How to generalize a comparison in Java code
How can I avoid repeating (display:flex, justify-content:center , aign-items:center) in my codes?I want to use them but I don’t want to repeat my self (DRY rule). is there any way to define a variable or something which contains those three lines? (WITHOUT USING SASS) >Solution : Make a template class for all flexboxes in your… Read More best practice for flex box
I’m trying have the HTML tag <br> interpreted as a line break, but instead it displays as a string literal in the view when I attempt this: <%= property.address_line_2 + "<br>" if property.address_line_2.present? %> I tried raw() and .html_safe but they the same effect. <%= property.address_line_2 + raw("<br>") if property.address_line_2.present? %> <%= property.address_line_2 + "<br>".html_safe… Read More Interpret interpolated html tag as html, not string literal?
For example, if I have 3 models that look like this: class CallLog(models.Model): lead_id = models.BigIntegerField("Lead ID") # other fields class EmailLog(models.Model): lead_id = models.BigIntegerField("Lead ID") # other fields class TextLog(models.Model): lead_id = models.BigIntegerField("Lead ID") # other fields Do I add lead_id to each model individually or is there a way to only type it… Read More If an app has multiple models with the same field, whats the best practice for keeping things DRY?
If async/await & callbacks are both asynchronous, why are async/await resolved before callbacks? For example (hypothetical, in practice its obviously not so cut-and-dry) // classic callback doSomething("./some-path", (err, data) => {…}) // This resolves with higher priority await someAsyncFunction() >Solution : In short, callbacks go to the end of the line in the regular job… Read More async/await vs callback resolution order, given shared asynchronicity
I have a row with 4 columns that are each 3 wide, which adds up to the 12 that are supposed the be in a row, but for some reason the last one is still going onto a new row. Any idea how to fix this? Here’s my code: <div class=”container text-center”> <h3>Welcome to “Ender’s… Read More Why is a column going into the next row when there are only 12 columns?
I’m writing a script that will run Windows commands for work ( I will convert it to an executable ). Eventually the script will have 10-15 buttons. How can I make it DRYer? from tkinter import * import os, ctypes, sys os.system(‘cmd /c "color a"’) root=Tk() root.title(‘Common Fixes’) root.geometry("1000×100") def is_admin(): try: return ctypes.windll.shell32.IsUserAnAdmin() except:… Read More Define multiple buttons for Windows commands
